    Description / Table of Contents: Zusammenfassung Die Liganden der Titelverbindungen1 und2 wurden aus dem entsprechenden Chalcon5 mit Hydrazinhydrat und anschließende N-N-Spaltung hergestellt. Die oestrogene Wirkung der Diamine11 und12 wurde im Rezeptorbindungstest an Kalbsuterus-Zytosol und durch einen Luziferase-Test an MCF 7-2a-Zellen bestimmt. Die Verbindungen wirken viel schwächer alsSchönenbergers aktivste Substanz ([meso-1,2-Bis(2,6-dichlor-4-hydroxyphenyl)ethan-1,2-diamin]dichloro-Platin(II),3).
    Notes: Summary The ligands of the title complexes1 and2 were prepared from the pertinent chalcone5 and hydrazine hydrate, followed by N-N cleavage. The estrogenic activity of the diamines11 and12 was determined by measuring the RBA values (calf uterine cytosol) and by a luciferase test in MCF 7-2a cells. The compounds are by far less active thanSchönenberger's most active compound ([meso-1,2-bis(2,6-dichloro-4-hydroxyphenyl)ethane-1,2-diamine]dichloro-platinum(II),3).

    Notes: Abstract Excitation spectra of the transitions 2P ΛA → 3D Λ and 2P Λ → 3PΛ in LiHe and LiNe collision molecules have been measured in the spectral range 15800–17600 cm−1 about the atomic Li2P → 3D line by means of two-step laser excitation. Rainbow satellite bands are observed and have been identified as due to maxima in the difference potentials 2PΣ-3DΣ, 2PΠ-3DΣ and 2PΛ-3PΣ, that are turn related to potential barriers in the upper 3PΣ and 3DΣ states. For identification of the satellites as well as understanding origin and shape of the potential barriers, approximate calculations were performed of interaction energies and dipole transition moments, that are based on the Fermi-Omont treatment of higher excited alkali-rare gas interaction. The satellite bands were analysed by means of semiclassical Uniform-Franck-Condon calculations of the spectra to yield values for characteristic parameters of the potential barriers. The results for position and height of the 3DΣ barrier are found to disagree more or less with values from different theoretical calculations.
